[PATCH for-4.17 v4 0/2] amd/virt_ssbd: refactoring and fixes

[Roger Pau Monne <roger.pau@citrix.com>]

Hello,

Just two patches remaining, and the last one is already Acked.

First patch deals with moving the switching of SSBD from guest
vm{entry,exit} to vCPU context switch, and lets Xen run with the guest
SSBD selection under some circumstances by default.

Andrew has expressed reservations to me privately with patch 2/2, but
I'm still sending it so that comments can be made publicly (or the patch
applied).

Thanks, Roger.
